Abstract

The invention discloses a caching system and method. The caching system comprises a server side and a client side. The server side is used for processing the cache key to obtain a database, a table and a sub-key corresponding to the cache key, storing the cache key and determining configuration information according to the database and the table, and sending the configuration information to the client side; and the client is used for receiving and storing the configuration information and managing the cache key in the server according to the configuration information. A cache key is processed;obtaining a database, a table and a sub-key corresponding to the cache key, hash coding and remainder taking are carried out on the database and the table; according to the method, the data and / or files belonging to the same database and table can be stored in the same storage set in the cache unit, the cache keys can be subjected to batch management according to the database and the table, the performance problem that a server side needs to perform whole-library overall scanning on the cache unit during deletion is avoided, and the method is high in speed, high in manageability and high in efficiency.

Description

technical field

[0001] The present application relates to the field of data storage, in particular to a caching system and method. Background technique

[0002] Cache refers to the memory that can perform high-speed data exchange. It exchanges data with the CPU before the memory, so the speed is very fast. When the CPU wants to read a piece of data, it first searches from the CPU cache, reads it immediately and sends it to the CPU if it finds it; The data block where this data is located is transferred to the cache, so that the entire block of data can be read from the cache in the future without calling the memory. Such a reading mechanism makes the CPU read cache hit rate very high (most CPUs can reach about 90%), that is to say, 90% of the data that the CPU will read next time are in the CPU cache, and only about 10% need to be read. Read from memory. It greatly saves the time for the CPU to directly read the memory, and basically does not need to wait for the CPU to r...
